Introduce usb_otg_add/remove_hcd() for use by host
controllers that are part of OTG/dual-role port.

Non Device tree platforms can use the otg_dev argument
to specify the OTG controller device. If otg_dev is NULL
then the device tree node's otg-controller property is used to
get the otg_dev device.

   Device managing a driver? That's interesting. :-)

Well it is the OTG controller instance really.
How else do you want me to write it?
